FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package easy-di
EasyDI
EasyDI是一个具有自动依赖注入的小型容器, 遵循PSR-11.
具体详细介绍及讨论请参见blog
容器提供方法:
-
raw(string $id, mixed $value)
适用于保存参数,$value可以是任何类型, 容器不会对其进行解析. -
set(string $id, \Closure|array|string $value, array $params=[], bool $shared=false)定义服务 -
singleton(string $id, \Closure|array|string $value, array $params=[])等同调用set($id, $value, $params, true) -
has(string $id)判断容器是否包含$id对应条目 -
get(string $id, array $params = [])
从容器中获取$id对应条目, 可选参数$params可优先参与到条目实例化过程中的依赖注入 -
call(callable $function, array $params=[])利用容器来调用callable, 由容器自动注入依赖. unset(string $id)从容器中移除$id对应条目
安装 Installation
Install EasyDi with Composer
composer require yjx/easy-di
基础使用 Basic Usage
容器的实例化
EasyDI容器管理两种类型的数据: 服务 和 参数(raw)
定义服务和参数
闭包中的参数
$c由于使用了类型指示, 因此EasyDI会自动完成依赖注入(将它自身注入).
自动依赖解决
示例1
直接拿PHP-DI官方演示代码
示例2
示例3 call()
php class UserManager { private $mailer;
public function __construct(Mailer $mailer)
{
$this->mailer = $mailer;
}
public function register($email, $password)
{
// The user just registered, we create his account
// ...
// We send him an email to say hello!
$this->mailer->mail($email, 'Hello and welcome!');
}
public function quickSend(Mailer $mailer, $email, $password)
{
$mailer->mail($email, 'Hello and welcome!');
}}
function testFunc(UserManager $manager) { return "test"; }
// 实例化容器 $c = new EasyDI\Container();
// 输出: 'test' echo $c->call('testFunc')."\n";
// 输出: 'test' echo $c->call(function (UserManager $tmp) { return 'test'; });
// 自动实例化UserManager对象 [$className, $methodName] $c->call([UserManager::class, 'register'], ['password'=>123, 'email'=>'[email protected]']);
// 自动实例化UserManager对象 $methodFullName $c->call(UserManager::class.'::'.'register', ['password'=>123, 'email'=>'[email protected]']);
// 调用类的静态方法 [$className, $staticMethodName] $c->call([UserManager::class, 'quickSend'], ['password'=>123, 'email'=>'[email protected]']);
// 使用字符串调用类的静态方法 $staticMethodFullName $c->call(UserManager::class.'::'.'quickSend', ['password'=>123, 'email'=>'[email protected]']);
// [$obj, $methodName] $c->call([new UserManager(new Mailer()), 'register'], ['password'=>123, 'email'=>'[email protected]']);
// [$obj, $staticMethodName] $c->call([new UserManager(new Mailer()), 'quickSend'], ['password'=>123, 'email'=>'[email protected]']);
